This was a great article. I found the following quotes most relevant. 'Partisan identity... fills “the void left when their other attachments wither away — religious, ethnic, communal and familial.” Beliefs are now so tied to these identities that data is not particularly useful to argue a point."'“To abandon facts,” he writes, “is to abandon freedom. If nothing is true, then no one can criticize power because there is no basis upon which to do so.” Timothy Snyder's pamphlet, which is mentioned in the article, can be found here.
